State and local authority must be contacted for necessary permits obtained before land application. Many permits require ongoing monitoring of groundwater and possibly soil and plant matter. Hydraulic loading is often ignored. If the site has a high water table or low permeability, the amount of water that can be applied generally is reduced. In some food processing waste, the level of salt is too high for land application. Most food processing waste land application sites should be designed by a professional who has experience in these type systems.
Today world is paying more attention to the issue of food and agricultural waste management is calling for more decisive action to be address on it. The growing awareness and increase in demand for proper action are rooted in strong moral connotations associated with food and agricultural waste management. These are based on the fact that food and agricultural waste implies unnecessary pressure on environment and natural resources. The land and water resources have been wasted, pollution created and greenhouse gases emitted to no purpose. It is also wonder how we ignore and allow food and agricultural waste thrown away when many hundred millions people in the world continue to hungry every day. This global attention on the issue of food and agricultural waste management is the main Agenda for Sustainable Development of st Century. Many countries are already taking action to reduce food and agricultural waste, but the challenges ahead remain significant and we need to step up efforts. When we strive to make progress towards reducing food and agricultural waste, it can highly effective in our efforts of best management of food cost, environmental problems and greenhouse gases. There is need to be considered main three dimensions. At first we need to know how much food and agricultural crops are wasted as accurately as possible, where and why Secondly we need to more clear about underlying reasons or objectives for reducing food and agricultural waste, must be related to food security and environment. Thirdly, we need to understand how food and agricultural waste, and its measures to reduce it, affect the objectives being pursued. These are the main points in order to help design more informed and better management policies for food and agricultural waste management. An estimation by FAO in suggested that around a third of the world’s food was lost and wasted every year. According to UN environment, globally around fourteen percent of the world’s food is lost from production before reaching to the retail level. The main objectives are reducing food and agricultural waste by better management and know how essentially environmental situation changes are. In the case of greenhouse gas these accumulate throughout the supply chain. Therefore, reducing food and agricultural waste by consumers will have the biggest impact which represents a larger amount of green gas house emissions.
The process of collection, transport, disposal, recycling and monitoring of agricultural waste is called food and agricultural waste management is undertaken to recycle the food and agricultural waste so as to reduce the ill effects of wastes on environment, health and aesthetics. Various techniques are used for the management of waste which includes land-filling, incineration, anaerobic digestion, pyrolysis, plasma gasification, recycling, composting. Anaerobic digestion produces bio fuel in the form of biogas. Plasma gasification results in the generation of electricity from waste. Recycling of food and agricultural waste involves the collection, sorting and reprocessing of waste into new products. Vermin composting is the preferred form of composting as it results in the formation of vermin compost called black gold due to the presence of rich nutrients and growth promoting factors in it.
The reduction of food and agricultural wastes is placed at the top of waste management hierarchies because the best means waste management is to reduce waste by not creating it in first place. The reduction of food and agricultural waste can also be achieved through the reuse of products. The reduction and reuse of wastes save natural resources, reduces generation of wastes and reduces the cost associated with food and agricultural waste disposal.
Food and agricultural waste management is undertaken to recycling the wastes so as to reduce the ill effects of wastes on environment, health and aesthetics. The waste may be either in solid, liquid or gaseous form. The process of food and agricultural waste management varies for rural and urban areas, for municipal and industrial waste, for developed and developing nations. The management of municipal wastes is responsibility of local government while as the management of agricultural waste is the responsibility of farmers. The developed nations use various novel technologies to reduce the negative impacts of waste or use and effective management to exploit it.
